The solution is, the percent of error, rounded to the nearest percent is 25%.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

While viewing a herd of cattle on a ranch, Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

now, we have to find the percent of error, rounded to the nearest percent.

so, we get,

Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

so, error = 750 - 600

              = 150

so, we get,

the percent of error = 150 * 100 / 600

                                 = 25%

Hence, The solution is, the percent of error, rounded to the nearest percent is 25%.

Therefore, Sam wrote a total of 38,789 digits. Therefore, the probability that Sam chooses a 0 is approximately 0.026. So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

In mathematics, probability is a measure of the likelihood or chance of an event occurring. It is a way of quantifying uncertainty and expressing how likely it is that a particular outcome will occur. Probability is calculated by dividing the number of outcomes that satisfy a certain condition (such as rolling a six) by the total number of possible outcomes. Probability theory is used in a wide range of fields, including mathematics, statistics, physics, engineering, economics, and social sciences. It is used to model and analyze random phenomena, make predictions, and estimate the likelihood of certain outcomes.

Here,

(a) Sam writes down all the positive integers from 1 to 9999, inclusive. To find the total number of digits Sam wrote, we can count the number of digits in each number and add them up.

Numbers from 1 to 9 have one digit each, so there are 9 numbers with one digit, for a total of 9 digits.

Numbers from 10 to 99 have two digits each, so there are 90 numbers with two digits, for a total of 180 digits.

Numbers from 100 to 999 have three digits each, so there are 900 numbers with three digits, for a total of 2700 digits.

Numbers from 1000 to 9999 have four digits each, so there are 9000 numbers with four digits, for a total of 36000 digits.

Adding up these totals gives:

9 + 180 + 2700 + 36000 = 38789

Therefore, Sam wrote a total of 38,789 digits.

(b) Since Sam chose the digits 1 to 9999, there are 4 digits (0, 1, 2, and 3) that can appear in the thousands place, and 10 digits (0 to 9) that can appear in each of the other three places.

Therefore, the probability of choosing a 0 at random is the number of times 0 appears in the numbers divided by the total number of digits written down.

0 appears as the last digit in 1000 numbers (from 10 to 9990), and as the first digit in 9 numbers (1000, 10000, 2000, 20000, 3000, 30000, 4000, 40000, and 5000). So the total number of times 0 appears is 1000 + 9 = 1009.

The total number of digits Sam wrote is 38,789, so the probability of choosing a 0 at random is:

1009/38789 ≈ 0.026

Therefore, the probability that Sam chooses a 0 is approximately 0.026.

(c) We can find the sum of all the digits Sam wrote by adding up the sum of the digits in each number from 1 to 9999.

The sum of the digits in the numbers from 1 to 9 is 1+2+3+4+5+6+7+8+9=45.

The sum of the digits in the numbers from 10 to 99 can be found by observing that each of the digits from 0 to 9 appears in the tens place the same number of times (that is, 10 times each). Since there are 90 two-digit numbers, each digit appears a total of 10 x 90 = 900 times in the tens place. So the sum of the digits in the tens place is:

900(0+1+2+3+4+5+6+7+8+9) = 45,000

Similarly, each of the digits from 0 to 9 appears in the hundreds place the same number of times (that is, 100 times each). So the sum of the digits in the hundreds place is:

100(0+1+2+3+4+5+6+7+8+9) = 4500

Finally, each of the digits from 0 to 9 appears in each of the four places (thousands, hundreds, tens, and ones) the same number of times (that is, 1000 times each). So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

Therefore , R(N) = 100 + 400 (N+1)(2N+1) + 800 x N2 N3 and area are the formulas for R(N) for the function f(x) = (5x)2 on [1, 5] and the function f(x) = (5x)2 in terms of N. R(N) = 767(approx) (approx).

Each x value in the domain has one but only one y value range, according to the rule of a function. Definition. If there is only one and only one value of x variable such that f(x) = y, then the function is one-to-one.

Here,

In the given question, we have to find a formula for R(N) for the function f(x) =(5x)^2 on [1, 5] in terms of N.

The given function is f(x)=(5x)^2 on [1, 5].

Ax = (5-1)/N

Ax = 4/N

X = 1+iAx

X = 1+i4/N

f(x) = 25X^2

f(x) = 25(1+i4/N)^2

f(x) = 25(1+i8/N+16/N^2 i^{2})

R(N) = 1ƒ(X) Ax

Now putting the value of f(x) and Ax

R(N)==1 [25 (1+ &i + 16i2)]

R(N) = 1001 (1 +Ni + 16i2)

N100 (1+i+12)N

100 (N += i +122)+16 N(N+1)(2N+1)(+1)(2N+1)

R(N)=100 (N + √2/ N(N+1) x 100

R(N) =2/6× N + 100 × 5 × N(N+1) + 100 x 2

\(\lim_{n \to \infty}\) R(N) = 100 + 400 + 800/3

\(\lim_{n \to \infty}\) R(N) = 766.67

\(\lim_{n \to \infty}\) R(N) = 767(approx)

Answer:

87.3%

Step-by-step explanation:

you got 3 candy bars. The cost for each is $0.89

So, 3 x 0.89= $2.67

Gave $5 and the difference between $2,67 is 2.33

5-2.67=2.33

The change was 2.33 and the cost was 2.67 so the % tip was

2.33/2.67= 0.873=87.3%

Answer:

Approximately 87.02% tip was left.

Step-by-step explanation:

The total cost of the three candy bars is 3 x $0.89 = $2.67.

so the total amount spent is $2.67.

You gave the cashier $5 and told them to keep the change, which is $5 - $2.67 = $2.33.

Therefore, the tip you left is $2.33.

To calculate the percentage tip:

(total cost of the three candy bars/the tip you left) x 100

which is equal to:

($2.33 / $2.67) x 100% ≈ 87.20%

So you left approximately an 87.20% tip.

Work out the first differences between the y-values:

\(7 \underset{-\frac{14}{3}}{\longrightarrow} \dfrac{7}{3} \underset{-\frac{14}{9}}{\longrightarrow} \dfrac{7}{9} \underset{-\frac{14}{27}}{\longrightarrow} \dfrac{7}{27} \underset{-\frac{14}{81}}{\longrightarrow} \dfrac{7}{81}\)

As the first differences are not the same, it is not a linear function.

Work out the second differences:

\(-\dfrac{14}{3} \underset{+\frac{28}{9}}{\longrightarrow} -\dfrac{14}{9} \underset{+\frac{28}{27}}{\longrightarrow} -\dfrac{14}{27} \underset{+\frac{28}{81}}{\longrightarrow} -\dfrac{14}{81}\)

As the second differences are not the same, it is not a quadratic function.

Work out if the second differences have a common ratio:

\(\implies \sf \dfrac{28}{27} \div \dfrac{28}{9}=\dfrac{1}{3}\)

\(\implies \sf \dfrac{28}{81} \div \dfrac{28}{27}=\dfrac{1}{3}\)

As the second differences have a common ratio of ¹/₃, the function is exponential with base ¹/₃.

General form of an exponential function:

\(y=a(b)^x\)

The value of the coin in 2019 would be approximately $132.

To calculate the value of the coin in 2019, we need to consider the annual increase rate of 16.9% from 2010 to 2019. We can use the compound interest formula to find the final value.

Starting with the initial value of $40 in 2010, we can calculate the value in 2019 as follows:

Value in 2019 = Initial value * (1 + Rate)^n

where Rate is the annual increase rate and n is the number of years between 2010 and 2019.

Plugging in the values:

Value in 2019 = $40 * (1 + 0.169)^9

Value in 2019 ≈ $40 * 2.996

Value in 2019 ≈ $119.84

Rounding the value to the nearest dollar, we get approximately $120. Therefore, the value of the coin in 2019 would be approximately $120.
